Fuel Saving Tips
Using the fuel which is cheapest at the pump may not be the cheapest fuel to use. I did an experiment filling up several times and logging the MPG at all the different outlets close to home. The outlet with the cheapest pump price was actually the most expensive returning a much lower MPG figure resulting in a significant increase in cost per mile.
